Hi Werner,
* about `trill_element` vs. `trillelement`: This was changed by Han-Wen in
commit c49e0fd544f (dated 2004) without any log messages. It looks
like an oversight that `trillelement` wasn't removed then.
Good to know! I'll put a further investigation/usage poll on the list of
side projects, unless someone else wants to head that themselves.
* About the rotated wiggle glyphs in Bravura: Do you have any idea why
this is so? If not, can you please ask the SMuFL people? It looks
definitely wrong to me! They should either correct the font or
provide glyph name aliases for horizontal typesetting (assuming that
glyph names, once introduced, can't be changed any longer).
There are far too much annoying things in OpenType for vertically
typeset scripts due to backward compatibility issues caused by
incapable typesetting systems. IMHO, today the proper technology
exists to avoid the need of horizontally composing glyph strings
that must be rotated afterwards.
I don't know... the SMuFL specs don't seem to say anything about it.
I'll message their list when I get the time.
* In your table I don't see a Bravura glyph
`ornamentZigZagLineShortened`. Is it really shortened that much so
that you no longer can see it? :-)
Nope! `ornamentZigZagLineShortened` is a name I thought up in lieu of a
SMuFL equivalent. It's a limitation of my coloring system that all
contentious mappings, whether suggested new glyphs or existing bravura
glyphs, show up the same red color.
Honestly, if SMuFL has no analogue to it and LilyPond doesn't even use
it anymore, we probably don't need to think too hard about the name of
this glyph. But I suppose -Alt might be more concise than -Shortened in
the meantime, with the added bonus that the -Alt suffix is attested
elsewhere in SMuFL. Anyone object to calling it `ornamentZigZagLineAlt`
until further notice?
